On April 28, 1988, an Aloha Airlines Boeing 737, N73711, based at
the Honolulu International Airport, Hawaii, was scheduled for a series of
Interisland flights to be conducted under Title 14 Code of Federal
Regulations (CFR) Part 121. A captain and first officer were assigned for
the first six flights of the day with a planned first officer change to
complete the remainder of the daily schedule.

The first officer checked in with the dispatch office about 0500
Hawaiian standard time at the Aloha Airlines Operations Facility. After
familiarizing himself with the flight operations paperwork, he proceeded to
the Aloha Airlines parking apron and performed the preflight inspection
required by company procedures before the first flight of the day. He stated
that the airplane maintenance log release was signed and that there were no
open discrepancies. He prepared the cockpit for the external portion of the
preflight, exited the airplane In predawn darkness, and performed the visual
exterior inspection on the lighted apron. He stated that he found nothing
unusual and was satisfied that the airplane was ready for flight.

The captain checked in for duty about 0510; he completed his
predeparture duties in the dispatch office and then proceeded to the
airplane.

The crew flew three roundtrip flights, one each from Honolulu to
Hilo, Maui, and Kaual. They reported that all six flights were uneventful
and that all airplane systems performed in the normal and expected manner.
Flightcrew visual exterior inspections between flights were not required by
Federal Aviation Administration (FAA) accepted company procedures, and none
were performed.

At 1100, a scheduled first officer change took place for the
remainder of the day. The crew flew from Honolulu to Maui and then from Maui
to Hilo. As with the previous flights of the day, no system, powerplant, or
structural abnormalities were noted during these operations, and the flights
were uneventful. Neither pilot left the airplane on arrival in Hilo, and the
crew did not perform any visual exterior inspection nor were they required to
do so.
